[5][6] The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of Na+/K+-ATPases.

These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle.

The catalytic subunit of Na+/K+-ATPase is encoded by multiple genes.

By manipulating this gene in the offspring of such mice, epilepsy can be avoided.
